the clinical meaning of external cervical resorption in maxillary canine transoperative dental trauma
Dental Press Journal of Orthodontics, 2014Co-Authors: Alberto Consolaro, Mauricio De Almeida Cardoso, Carolina Dornelas C M De Almeida, Ingrid De Araujo Oliveira Souza, Leopoldino Capelloza FilhoAbstract:External Cervical Resorption in maxillary canines with pulp vitality is frequently associated with dental trauma resulting from surgical procedures carried out to prepare the teeth for further orthodontic traction. Preparation procedures might surgically manipulate the Cementoenamel Junction or cause luxation of teeth due to applying excessive force or movement tests beyond the tolerance limits of periodontal ligament and cervical tissue structures. Dentin exposure at the Cementoenamel Junction triggers External Cervical Resorption as a result of inflammation followed by antigen recognition of dentin proteins. External Cervical Resorption is painless, does not induce pulpitis and develops slowly. The lesion is generally associated with and covered by gingival soft tissues which disguise normal clinical aspects, thereby leading to late diagnosis when the process is near pulp threshold. Endodontic treatment is recommended only if surgical procedures are rendered necessary in the pulp space; otherwise, External Cervical Resorption should be treated by conservative means: protecting the dental pulp and restoring function and esthetics of teeth whose pulp will remain in normal conditions. Unfortunately, there is a lack of well-grounded research evincing how often External Cervical Resorption associated with canines subjected to orthodontic traction occurs.

Morphology of the Cementoenamel Junction of primary teeth.
Journal of dentistry for children (Chicago Ill.), 2008Co-Authors: Leda A. Francischone, Alberto ConsolaroAbstract:Purpose The purpose of this study was to investigate anatomically the Cementoenamel Junctions (CEJs) of primary teeth by observation of the morphological relationship among enamel, cementum, and dentin. Methods One hundred five human extracted primary teeth were analyzed by scanning electron microscopy. The teeth were divided into 7 groups, each with 15 primary teeth, as follows: maxillary central incisors (group 1); maxillary lateral incisors (group 2); maxillary canines (group 3); maxillary molars (group 4); mandibular incisors (group 5); mandibular canines (group 6); and mandibular molars (group 7). The entire cervical region was analyzed, especially concerning regularity of the CEJ, for establishment of the type of enamel-cementum relationship (cementum over enamel, the edge-to-edge relationship between cementum and enamel, and presence of gaps with exposure of dentinal tubuli). Results All circumferences represented by CEJs exhibit an interchange and combination of 3 types of relationships: (1) cementum over enamel; (2) enamel and cementum in the edge-to-edge relationship; and (3) the presence of a gap between the enamel and cementum with dentin exposure. There was no predominance as to the dental groups. Conclusions All primary teeth exhibited the 3 morphological tissue interrelation types along the circumference of the Cementoenamel Junction. The irregularity and fragility of Cementoenamel Junction structures indicate that this region is weak and should be handled with care and protected during application of chemicals and utilization of clamps, dental instruments, and restorative materials.

Cementoenamel Junction: Microscopic Analysis and External Cervical Resorption
Journal of endodontics, 2000Co-Authors: Lilian Neuvald, Alberto ConsolaroAbstract:There is a lack of data regarding the shapes and distribution of the mineralized tissue that composes the Cementoenamel Junction. A sample of 198 permanent human teeth was analyzed by optical microscopy and scanning electron microscopy. Scanning electron microscopy showed three types of tissue interrelations: enamel overlapped by cementum; enamel and cementum edge-to-edge; and a gap, revealing a strip of exposed dentin. Using optical microscopy, a fourth type of Cementoenamel Junction was observed: cementum overlapped by enamel. The distribution of the hard tissues found at the Cementoenamel Junction is unpredictable and irregular both for any tooth type (e.g. on cuspids) and on any one individual tooth. Based on these results and on analysis of the mechanisms involved in cervical root resorption, it is possible to consider the cervical region as prone to external resorption.

uncommon dentigerous cyst related to a maxillary lateral incisor in a 03 year old boy
Oral and Maxillofacial Surgery, 2012Co-Authors: Luciana Soares De Andrade Freitas Oliveira, Delano Oliveira Souza, Frederico Sampaio Neves, Jean Nunes Dos Santos, Paulo Sérgio Flores Campos, Ieda CrusoerebelloAbstract:Background The dentigerous cyst is usually defined as a cystic cavity that surrounds the crown of an unerupted tooth on the Cementoenamel Junction. The present article reports a case of an uncommon dentigerous cyst, highlighting its clinical, radiographic and surgical characteristics and discussing the aspects related to its development in infancy.

Uncommon dentigerous cyst related to a maxillary lateral incisor in a 03-year-old boy
Oral and Maxillofacial Surgery, 2012Co-Authors: Luciana Soares De Andrade Freitas Oliveira, Delano Oliveira Souza, Frederico Sampaio Neves, Paulo Sérgio Flores Campos, Jean Nunes Santos, Ieda Crusoé-rebelloAbstract:Background The dentigerous cyst is usually defined as a cystic cavity that surrounds the crown of an unerupted tooth on the Cementoenamel Junction. The present article reports a case of an uncommon dentigerous cyst, highlighting its clinical, radiographic and surgical characteristics and discussing the aspects related to its development in infancy. Case report A 03-year-old boy patient presented with an extensive radiolucid area involving the crown of the right maxillary lateral incisor. A surgical excision was performed. Anatomopathological examination revealed a cystic tissue with a fibrous wall surrounded by nonkeratinized stratified squamous oral epithelium, without atypia. Conclusion It is possible that the dentigerous cyst grows in the dental germ in any stage of development and not only in the follicle of a tooth with calcified crown attached to the Cementoenamel Junction.

Bilateral talon cusp on maxillary incisors: A unique case report
International Journal of Oral Health Sciences, 2013Co-Authors: Anusha Rangare Lakshman, Sham Kishor Kanneppady, Chaithra KalkurAbstract:The talon cusp, or dens evaginatus of anterior teeth, is a relatively rare dental developmental anomaly characterized by the presence of an accessory cusp-like structure projecting from the cingulum area or Cementoenamel Junction. This cusp resembles an eagle's talon and hence is named after it. It usually contains normal enamel, dentin and, sometimes, extending into the pulp. Most of the cases are unilateral and only one-fifth of the cases are bilateral. We are hereby highlighting a rare and distinctive presentation of talon cusp involving the bilateral maxillary incisors.
